This case report highlights a rare instance of fingernail and toenail hyperpigmentation following the use of valproic acid, which resolved after discontinuation of the drug.

This case report suggests that poor hair and nail growth in children with autism spectrum disorder and developmental delay may indicate a biotin-responsive condition, as biotin and acetazolamide therapy improved symptoms and school performance in the reported patient.

This review discusses the classification, pathogenesis, and management of skin, hair, nail, and mucosal changes due to EGFR inhibitors, emphasizing the importance of informing patients to improve therapy compliance.

This article reviews hair and nail disorders in children, emphasizing their prevalence, congenital and acquired origins, and the diagnostic challenges compared to treatment, but reports no new clinical results.

Different nail disorders are treated by targeting their specific causes and using appropriate medications or protective measures.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

This case report describes a father with HOXC13-associated pure hair-nail ectodermal dysplasia, presenting with severe nail dystrophy affecting all digits and notable hypotrichosis or complete alopecia.

This article illustrates various hair shaft defects and suggests that dermatologists can diagnose most of them using light microscopy and polarization without needing advanced imaging techniques.

This study observed that Ptprq mutant mice exhibit significant abnormalities in hair bundle structure and vestibular dysfunction, suggesting similar issues may contribute to hearing loss and vestibular problems in humans with PTPRQ mutations.

This study found that fish oil supplementation in male Wistar albino rats helped maintain hair shaft structure and improved amino acid composition, while reducing harmful protein compounds associated with diabetes and hypercholesterolemia.

Men with a certain type of hair loss often use facial moisturizers, and a specific antibiotic treatment may help another hair condition.

This article reviews drug-induced hair and nail disorders and discusses their clinical recognition, underlying mechanisms, and potential treatment strategies, without presenting new research findings.

This article presents an update on a family with Coats' plus disorder, documenting additional symptoms and two new similar cases, and reviews literature suggesting a link to dyskeratosis congenita for potential molecular insights.

This overview details the Dermatologic Surgery journal's focus on various dermatologic surgical procedures, but it presents no new research findings.

This study found that loss-of-function mutations in the HOXC13 gene cause autosomal-recessive pure hair and nail ectodermal dysplasia, emphasizing its role in hair and nail development.

Experts discussed treatments for skin conditions in children, emphasizing hydration, cautious medication use, and early intervention for infections.
